The M-1943 Field Jacket became a standardised garment in 1943, during the latter stages of World War II as improved combat uniform. It was developed based on feedback from the M-41 jacket, which had been hastily designed in response to the growing likelihood of U.S. involvement in the war. The M-43 was a significant upgrade, addressing issues of durability, comfort, and adaptability for fluctuating climates.

After its introduction, the M-43 underwent several specification updates. The most notable was the transition to “Pattern B,” which included modifications to accommodate a dedicated liner - the JACKET, FIELD, PILE, O.D. This change resulted in an oversized fit and began with the 370D specification, with contracts issued in February 1944. Overall, six specification types were developed, ranging from 370 to 370E. However, the 370 and 370A were prototypes, with the 370B being the first version used in active service. Early models, such as the 370B and 370C, are distinguished from later ones, including the 370D and 370E, which represented the final and definitive design.

One clear distinction between early and late models lies in the pocket flap shape. Early versions featured narrow, triangular flaps, while later versions introduced wider, home-plate-shaped flaps, a design element that would later influence the M-65 Field Jacket. This reproduction faithfully replicates the 370E specification, widely regarded as the ultimate version of the M-43 Field Jacket.
